Abstract: An efficient algorithm DNA-based Symmetric Key Algorithm (DNA-SKA) for generating secret keys for sensor nodes is proposed in this paper. The key feature of the proposed algorithm is the usage of a DNA sequence as an initial key which is proffered to be selected from National Council of Biotechnological Information (NCBI) database available publically. Authentication process is required to make a secure communication between nodes. The Base Station then provides both nodes with two unique DNA strands generated by the unwinding of a single DNA molecule selected from NCBI database. The nodes then perform a simple but ingenious mechanism on the strands to obtain a similar symmetric key to be used for further encryption of the data to be communicated between the nodes. Computationally, it is a light-weight algorithm and better suitable for devices like sensor nodes because of their limited computing resources.

Keywords: wireless sensor networks; DNA computing; DNA replication; DNA cryptography; DNA steganography.
